Hello Matthew, You mean the only added value of APR is for TLS when Java version doesn't support some cipher suites.
Best Regards. -----Original Message----- From: Matthew Broadhead [mailto:[email protected]] Sent: mardi 7 novembre 2017 11:20 To: [email protected] Subject: Re: Question about APR APR is essential if Java doesn't support the encryption algorithm of the SSL / TLS certificate provided by your Certificate authority. It allows Tomcat to be trusted by your OS to use the system libraries (e.g. OpenSSL). The system libraries can also be faster under certain conditions. Only applies if you need a Connector->SSLHostConfig->Certificate in server.xml.
